The order numbers of the individual components (du/dt reactor and voltage peak limiter) are
listed in the following table:

Voltage Peak Limiter
Fast-switching IGBTs in the converter result in high voltage gradients du/dt at the converter
output. If long motor cables are used, this leads to an additional current load on the
converter due to capacitive charge/discharge currents. The high voltage gradients, and the
resulting transients at the motor terminals, cause the motors' electrical winding load to
increase as compared with direct on-line operation.
The du/dt filter plus Voltage Peak Limiter limits the rate of voltage rise to values < 500 V/µs
